Ubuntu Networking :: Internet Doesn't Work After Upgrade
Jan 4, 2010
I just upgraded from 9.04 to 9.10. When I restarted, I admired the new login menu, then went to Firefox. I noticed that my wireless didn't work (it did in 9.04) Thinking I'd just need to reinstall the drivers, I plugged in the computer to a working Ethernet outlet with a working cord. I noticed that Ubuntu didn't tell me that Auto eth0 was connected. It didn't tell me anything. And then I went to Google and realized that the wired connection didn't work either. Then I came here on an iPod Touch and you know the rest.
Edit: And other devices work too on the network.

Hello.
I've openSUSE 11.2, 64-bit version, with GNOME desktop.
My hardware is a Conceptronic c150ru.
Well, I configured it with Ndiswrapper (http://en.opensuse.org/Ndiswrapper_howto), and I hadn't problems.
Then, I tried to enable Internet with the terminal. Firstly, I wrote iwconfig wlan0 mode managed. Well.
Secondly, I wrote iwconfig wlan0 essid (my essid). Well.
Then, I wrote iwconfig wlan0 key (my key wep). An error message appears. How can I write my key wep?

I have a desktop pc with xubuntu 9.10 32bit installed. I don't have direct access to this machine, but they told me that internet is not working (firefox, synaptic,etc...), but only skype works! If they reboot on windows, everything works well, so it's not a matter of connection or dns.It's very important because they work with that computer. How can i solve the problem? and what could be the cause of this strange anomaly

I have a WUSB54GC v.1 wireless USB adapter which I use to connect to my home network. For some reason, over time my reception has been getting worse. I'm not sure if this is due to the router or the adapter. In addition, when the signal strength dips below 50%, I can no longer receive email or browse the web. This is only a problem with Ubuntu - when I had WinXP installed, I could access the internet mostly regardless of the signal strength.
I started a year ago with the adapter plugged directly into the computer. After a while I found it necessary to use an extension cord to place the adapter outside my room, closer to the router. A while later it was time for another extension cord, and now my reception has gotten worse again, but I can't extend it any further.

I am running the latest ubuntu and I am having trouble getting networking sorted. I have 2 networks, one wired (eth0) and one wireless (wlan0). I connect to the internet using wireless. The problem is that I can only successfully connect to the internet if I disconnect from eth0. I have hit this problem with Windows machines and the solution was to adjust the "interface metric" in "Advanced TCP/IP Settings" so that the wireless was the preferred connection. How can I achieve something similar in Ubuntu?

today i installed ubuntu 10.10 on my hp mini 210 netbook. previously i had ubuntu netbook remix running and had no problem accessing the internet both wired and wireless; however, since installing 10.10 i have been searching for a solution for the last six hours but have been unable to get either to work.
as far as hardware is concerned i have a broadband bcm4313 802.11 network controller and am running through a linksys router which i know to be working because i have 4 other computers connected to it all with internet access. i checked ifconfig and a lo conection was listed but no eth0. i also tried downloading a broadband tar.gz driver but dont have any packages to build it and cant get any since the computer has no internet. i assume wired is easiest to setup so lets start there even though i use wireless 90% of the time. im new to linux so please dont expect me to know any terminal commands.

I recently installed Fedora 15 x86_64 on my new AMD Machine and I'm quite pleased with things thus far.Here's where my problem comes. I mainly bought that machine to help me with Development. More specifically, Virtual Machines for testing purposes. I have installed Fedora 15 x86_64 as a qemu-kvm Virtual Machine and it's working.. for the most part. I am having a whole lot of trouble getting it to connect to the Internet.
My guess is the only way I'm going to reliably do that is to setup a Bridge. Yes/no? However, in order to setup a Bridge I need to disable NetworkManager and that where the fun happens. It completely disables my network connection. I'm probably missing something small, but I can't figure out what I'm missing. I've double checked my ifcfg-em1 multiple times(I've been trying for ~24 hours so far) and all the settings are as they should be.
I've turned NetworkManager off and stopped it(chkconfig and service) and turned network on(chkconfig and service). Theoretically I should simply need to turn off NM and turn on network and things should be fine. no?
Well, aside from adding:
ONBOOT=yes
NM_CONTROLED=no
to ifcfg-em1.

I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.
Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?

I can't connect to my ssh-server (on ubuntu 10.04) from any external address. The error in putty is "connection timed out". From my internal network, everything works fine, even if I select my external IP address and port in putty as the destination.
This is what I have done so far:
installed open ssh with the ubuntu server 10.04 cd
set up port forwarding (11041) in my router (seems to work ok, port is open according to "shields up")
configured ssh to use port 11041 in /etc/ssh/sshd_config
changed tcp and udp ssh port in /etc/services to 11041
enabled UFW and did sudo ufw allow ssh

Before ubuntu can even boot I get this on my monitor Out of range set to 1280x1080 60Hz I get that a grub. I'm not even sure if ubuntu can even boot because my monitor won't let me see anything. I'm using the driver off the nvidia website, not the stock one that came with ubuntu.

I'm just a newbie to this operating system. Even though I'm having some trouble, it still seems more sensible to me than Windows. I'd like to continue to use it, but I'd like to know why it doesn't work for me sometimes, and I'd like to see if I can't make it work better for me.
After I upgraded to 11.04 I've had a host of problems. My USB ports have intermittant trouble recognizing storage devices. My USB ports also have intermittant trouble recognizing my USB WiFi device. The VLC player will crash the Gnome Desktop whenever I use it. I still haven't figured it out.
I'm interested in the following question:
Why can't software and hardware that already works be insured to continue to work after an upgrade?

I've just upgraded to Ubuntu 11.04. Everything worked fine, until I rebooted. Now I can not connect to my home wireless internet, so I can't re-enable third party software sources. I am currently using a different computer, so I know that our internet works. I checked the wireless switch on my laptop, and it says that wireless is enabled. I've rebooted, and it still doesn't work. I tried our wired internet, and that didn't work either (although I'm not sure if our wired internet works; we haven't used it in a few years)

I have just dual booted my pc to run windows 7(64 bit) and ubuntu 9.10 (64 bit). This is my FIRST time using ubunutu and i have spent the whole day trying to get my internet working but with no success. I have come so close to giving up on ubuntu but for some reason i just cant let go! When i type in ifconfig in the terminal i can see that i have an ip address assigned and i can ping my router. My motherboard came with linux drivers and i tried installing the LAN drivers with the included instructions i have got no where. I did find out that the file name in the instructions was wrong and the actual name is r8168-8.012.00. Here are the instructions-

I had been running Slackware64 13 almost since it came out and recently upgraded to Slackware64 13.1.Every thing looked to be working well until I tried to burn a DVD with k3B. It starts the burn process but then dies and says that "cdrecord has no permission to open the device".I was able to put in a DVD+RW and erase it without a problem, but when trying to burn to a DVD-R it stops and gives me the error.I checked cdrecord and it is owned by root in the root group.

After I finished upgrading Xubuntu from 9.10 to 10.04, I discovered that my keyboard stopped working in X Server. The upgrade process was running smoothly until the last moment, when it produced some error, which I, unfortunately, did not write down. Anyway, the upgrade has completed; uname shows kernel version 2.6.32-31. Now the keyboard works fine if I select a recovery mode at startup, but if I type 'start gdm' from the shell or select the default option in GRUB while booting, the keyboard becomes unavailable right from the login screen. I can log on using the virtual keyboard, but that's all I can do; the keyboard is still dead.

My webcam worked with every application in Linux Mint6. I just upgraded to Ubuntu 8.04 and find that the input from the webcam looks like a green TV without horizontal lock in Camorama and Skype. However it works perfectly with Cheese.

This weekend I did a distribution upgrade to Karmic, but it didn't go very well. Upon reboot, I see a white ubuntu logo on a black screen. I hear the speakers pop, and the screen flashes several times, sorta like the blank screen is maybe changing video modes. After a while I see what I think is garbled text but is unreadable, and it looks like I can log on even though I can't read anything. Now, booting into recovery mode gets me to a readable prompt. There are no upgrades to apply. Typing gdm from here gets me to the desktop just fine. Also when booting, if I choose an earlier kernel the system boots fine also, except the touchpad doesn't work.

After the upgrade, I've noticed a problem I haven't had before - hibernating worked fine to the last. The problem is, although the system correctly hibernates, it makes no attempt to "wake" from hibernation when I power it up - it boots normally, and with fsck-ing like it was powered off without proper shutdown (understandably). I don't know why it happens, and I've skimmed the logs, but noticed nothing special. What could be the problem? What could I try? Which log should help someone find that out?

I recently tried to upgrade my Dell Latitude C610 from 10.10 to 11.04, but it got kernel panic right in the middle. Now it at least boots, but the mouse doesn't work--only the keyboard does. How do I fix this enough to use the mouse, or how do I operate Gnome with a keyboard?
